The MAPX audio processor is an integrated, high-performance audio system-on-chip (SoC) for soundbars, speakers, entry level AV receivers, home theater systems and integrated audio systems. MAPX is extremely versatile and allows developers to design a wide variety of end products with minimal incremental PCB design effort because of the commonality of device variants across the range. All MAPX solutions are designed to be software compatible with each other and pin-to-pin compatible for the same package. This makes it easy for develope....

MAPX is a product of Qualcomm Technologies International, Ltd.

Family concept for device compatibility

The MAPX series of SoCs includes seven sub-families that are available in one of two pin-compatible package types. The entire family of MAPX SoCs are designed to be software compatible, to help make it easier for developers to switch between different devices to create unique products with varying feature sets.

Extensive range of processing technologies available

MAPX audio processors include a range of processing technologies, including the royalty-free Qualcomm® meloD™ audio processing suite, extensive lip-sync audio delay and third party processing from Dolby, DTS and others.

Maximum differentiation with almost unlimited flexibility

Helping manufacturers to realize maximum differentiation with the DSP code download option and Customizable Modular Processing (CMP), MAPX supports custom algorithms and filters by providing a C-language SDK.
